I WHITE, OF'SAME PLACE.

CAR-AXLE LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 437,394, dated September 30, 1890. Application filed February 13, 1890. Serial No. 340,829. (No model.)

To all whom it may concern.-

Be it known that I, ABE L. CUSHMAN, a citi zen of the United States, residing at Concord, in the county of Merrimac and State of New Hampshire, have invented certain new and useful Improvements in Car-Axle Lubricators, of which the following isa specification.

My invention relates to improvements in car-axle lubricators in which a block of felting operates in conjunction with a chair or support having journal-bearings at one end, in which oscillates a journaled receptacle containing felting or wicking for the purpose of lubricating car-axles; and the objects of my improvements are, first, to provide a sure and simple method of oiling car-axles; second, to secure a perfectly-lubricated bearing; third, to prevent the heating of the journals as heretofore. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a isometrical view of the lubricator in position in the box or housing. Fig. 2 is a partial longitudinal cross-section of the lubricator and housing through the center.

Similar letters refer to similar parts through the several views.

The weight C, its support F, and the case or receptacle E constitutes the frame-work for the lubricator. The support F has a fulcrum-point 0, adapted to rest on the bottom of any ordinary car-axle box or housing near the center of its entire length, and at one end of the said support is a boss or lug on either side of the case or receptacle E, through which passes the journals 1) b, secured to the opposite sides of the receptacle E, thereby allowing the felting D to keep an equal bearing on the journal B at either end of the felting by the oscillating movement of its journaled bearings 19, and to take up any wear that may be caused by the journal B or irregular wearing of the same, the bottom of the said receptacle E being on a circle to allow this adjustment, and also to allow the felting to come down to the bottom of the receptacle E, and to nearly touch the bottom of the box or housing A. The other end of the said support F is supplied with a weight of the proper size to hold the felting or wicking D in contact with the journal B, the fulcrumpoint 0 being of the required height to allow this adjustment. The casting or support F is also provided with projections a a, nearly touching the housing on its side to keep the lubricator Within proper bounds within the housing A, and also to prevent any displacement of the same when on the road. The fulcrum-point could be in any place on the lower part of the casting or support F. For instance, it could be nearer the lugs on the end of the casting F and allow a smaller weight C to hold the felting D in contact with the journal B.

The lower part of the receptacleE could be of any shape it it was made to come down and nearly come in contact with the lower part of the housing A, and thereby taking the oil from the bottom of the housing and depositing it on the journal B, as the felting is always saturated with oil as long as any oil remains in the box or housing, and thereby assuring a perfectly-lubricated hearing.

I am aware that prior to my invention lubricators have been made that operate in conjunction with felting or winking. I therefore do not claim the combination, broadly; but

What I do claim is- 1. A car-axle lubricator provided with a casing or a receptacle E for the purpose of containing the felting or wicking D, and thesaid receptacle provided with journals on opposite sides adapted to oscillate in the bearings secured to one end of the casting or support F to allow awvertical movement of the aforesaid receptacle, and also to allow the felting or wicking to keep an equal bearing on the journal, as set forth and described.

2. A car-axle lubricator provided with a casting or support F, having a fulcrum-point 0, adapted to rest on the bottom of the box or housing A, the aforesaid support supplied with a weight C of the proper size to hold the felting or wicking in contact with the journal and to take up any Wear in the journal B or the felting D, as herein set forth and de scribed.

ABE L. CUSHMAN.
